I initially separated my hen from the rest of the girls, she no longer accepted her mushed food and didn't seem to drink much, that's when I decided to put her back out, she was happier. Now when I vomit her, I do it outside the coop and put her back in with the girls. They wont reject her, the pecking order might change due to bombie not feeling well. Put some Vaseline on were she has been injured. Hope you see some improvements in the morning.
